Rajiv Gandhi National Park, Nagarahole is one of the hot spots for wildlife in the Nilgiri Biosphere Reserve (Western Ghats), Karnataka State. The national park covers an area of 643.4 sq. km. with a core zone of 192 sq.km. The terrain undulating with an altitude ranging from 701 to 959 m asl. Monsoon is erratic, but it generally rains from June to September with an annual rainfall of about 1,440 mm and temperature range is 14ºC-33º C. Anuran calls at the breeding season is one of the principal means of guidance for individuals of a species to gather at suitable breeding sites. The call of each species is distinctive and is a good guide for field identification. Since the development of sound analysis techniques, the comparison of advertisement calls of different populations has played a major role in the detection of cryptic species worldwide. Acoustic studies of anurans were carried out in the region during rainy seasons between 2013-2014. Acoustic call features of 5 anuran species were analyzed in the present study. These included Euphlyctis hexadactylus, Fejervarya granosa, Microhyla ornata, Ramanella triangularis and Clinotarsus curtipes.
